Answer:
Impulse =14937.9 N
tangential force =14937.9 N
Explanation:
Given that
Mass of car m= 800 kg
initial velocity u=0
Final velocity v=390 km/hr
Final velocity v=108.3 m/s
So change in linear momentum P= m x v
P= 800 x 108.3
P=86640 kg.m/s
We know that impulse force F= P/t
So F= 86640/5.8 N
F=14937.9 N
Impulse force F= 14937.9 N
We know that
v=u + at
108.3 = 0 + a x 5.8
![a=18.66\ m/s^2](https://tex.z-dn.net/?f=a%3D18.66%5C%20m%2Fs%5E2)
So tangential force F= m x a
F=18.66 x 800
F=14937.9 N

umm can you explain me what i have to answer
Answer:
(c) Inconel 600 and nickel 200
Explanation:
In order to make this prediction one will have to make use of the Galvanic series of metals in seawater table. The closer two metals are in the table the less likely they will corrode. The further away two metals are in the table the more likely they will corrode.
(a) Aluminum and magnesium together, there is possibility of corrosion.
(b) For the zinc-low carbon steel couple, corrosion is possible, and zinc will corrode.
(c) For Inconel 600 and nickel 200, corrosion is unlikely as both alloys appear closer on the table.
(d) The titanium and 304 stainless steel pair, the stainless steel will corrode. As long as it is below Titanium in both its active and passive states.
(e) For the cast iron and 316 stainless steel pair, the cast iron will corrode since it is below stainless steel in both active and passive states.

When a lamp is connected to a wall plug, theresulting circuit can be represented by a simplified AC circuit, asshown in the figure. (Part B figure) Here the lamp has been replaced by a resistor with an equivalentresistance Part B figure) Here the lamp has been replaced bya resistor with an equivalent resistance R = 120 . What is the rms value Irms of the current flowing through the circuit?
Express your answer in amperes.
Irms = ? A
